Mortification of Sin Guide

"For if you live according to the flesh you will die, but if by the Spirit you put to death the deeds of the body, you will live." — Romans 8:13

As we work through Romans 8:9–13 together, Pastor Brian has pointed us to one of the most practical and sobering callings of the Christian life: putting sin to death. Scripture doesn't invite us to manage our sin, excuse it, or keep it around like a pet. It calls us to kill it, not in our own strength but by the power of the Spirit who lives in every believer.

This guide is meant to help you do that. Drawing on John Owen's classic work The Mortification of Sin, it walks you through what mortification is, who can do it, and how to fight sin with the gospel at the center.

Mortification is hard, honest work, but it is always a work of grace. We don't fight for forgiveness; we fight from it, resting securely in the Father's love.
